Lethbridge Herald, The (Newspaper) - May 16, 1972, Lethbridge, Alberta 2G THE LETHBRIDGE HERALD Tuesday, May 14, 197? Irrigated pastures on native prairie I5y SITlvr SMOMAIC I.clliln-iilgr Research Million pcTsliirt's tvtti IK? e.s- lablisiiwl successfully on na- tive prairie if cerlnin man- agement and irrigation prac- (ices are employed.

During Ihc past two years we have been conducting tests lo determine the best method of oslabhsh i n g irrigated pasture on nalivc grassland. Our si tidies included cultiva- tion by rololiller, application of herbicides, and dales of seed- ing, alone and in various com- binations. Some plots were ro- totilled and seeded in early May, others in mid Applications of Paraquat a I tu'o pounds per acre or a mix- ture of at two pounds per acre and dalapon al 14 pounds per acre were made in mid- June. The plots were seeded at. 20 pounds pur acre lu a pas- ture mixlme comprising Five pounds of orchardgrass, eight pounds of brome, five [HKinds of creeping red fescue, and two pounds of while clover. The mast successful pasture rc.suHed when we rotolilled in early May and irnmcdialoly seeded the pasture mixture.

Warm spring could aid grasshoppers An early, warm spring rmiW mean a considerable grasshop per outbreak on the prairies. Most of it will be moderate to light, however. The information conies from reports received from Ihc en- tomology sections of the Can- ada department of agriculturo research sin lions al Winnipeg, Man., Saskaloon, and Lel.hbridge. Weal her conditions over I ho three prairie- provinces wore fa- vorable for the pral-s in 1971. An early halch in mosl areas, followed by a dry .summer and a long fall, coulribuled lo (he e.'icly developmenl oi and an extended egg laying period. In Manitoba, the forecast in- fested area is more than eight times larger than lasl year. There are square miles infested, of which 2.010 are light, moderate and UQ severe. The largest and most heavily- hifeslcd area is Ihc lied Hivcr Valley. Most of I his area is moderately infested and is sur- roiimlal by an area of light in- flation. The forecast area for kalchcwan is more than three times that of 1971. There am sYiu.vrc miJc.s infeslcd, nt which are light and Iho remaining l.niiil moderalc. The area infested with grass- hoppers in Alberta lias also more than tripled from Of the square miles in- fested, arc in the light category and the remainder in Lhe moderate. There arc three main areas of moderate infoslaiion in tho province and a considerably l.irgcr area of light a good portion of which is in cast central Alberta liolween the Baltic and the Rod Deer Rivers. The three are: Glenlca, a new feed wheat variety developed by the Uni- versity of Manitoba. Puma, a new fall rye va- riety developed by the Univer- sity of Manitoba. Trent, a new barley well suited to production in sniiih- wosfern Ontario. It was devel- oped by the University of Guelpli. The varieties have been li- censed by the Plant Products Division of the Canada Agricul- ture Production and Marketing Branch. Glcnlca is a high yielding feed wheal developed out of a background of Mexican wheal vanoUc.s. Yields arc highest in I lie moir.tor areas of Manitoba and oi her parts of the Prairie Provinces wheie moisture is not a severe limiting factor. The original croa.s was in and selection for im- provement has been on in Winnipeg and Mexico for five generations. fllrnlea is superior to both iVrqK.wa and Pitic (i2 in yield- ing ability hi areas where moisture is sufficient. Its bush- el weight is essentially equal lo Neepawa, but its kernel weight is onc-lhird grcaler. The size and color of its ker- nels make it easy (o clis- Linguish from hard red spring wheat varieties. It matures one to two days later than Neepawa. II is rnsLslant to prevalent races of leaf and slcm rust, is resistant lo common root rot and to loose smut and head discoloration. Puma is a new fall rye va- ricly which has excellent win- ter hardiness, filial to Froiv- tier and superior to Cougar. It is higher yielding than oth- er winler-hardy varieties now produced in western Canada and it has larger seeds. Pedigreed and breeders seed will be distributed by the de- partment of plant scienca at the University of Manitoba in co-operation with the Cana- dian Seed Crowd's Association. Seed will be available in lime for fall planting this year. There is a polcnlial for high- er yields from Trent., n new yel- low alemone feed type six-row- ed barley, because it has strong .straw and responds well to fertilizer. It may IHJ of considerable value Lo fanners in soulhwest- ern Ontario. The crop science department of Iho University ot Guclph is maintaining supplies of breed-, cr seed. T rent has heller straw strength and yield ttian York and P.rock and has genetic re- sislance to prevalent races of loose s in u L, powdei-y mildew, stem rust and septun.i. It resembles Brock in ap- pnarance and, like Brock, i-i classed as non-malting and nut eligible fm grades higher than Number 1 feed.
